I will explain our setup and the issue in detail to make the situation fully clear.
Our Project Setup
Jira Cloud
Team-managed project (not company-managed)
We are intentionally not using Epic Link
We are using the new hierarchy model based on:
This approach is based directly on Atlassian’s official documentation for CSV imports using Work item ID and Parent.
Despite the correct behavior above, the import always finishes with warnings such as:
"Cannot add value [ Work item ] to CustomField [JTE-XXX] in Epic Link.
Probably value was in incorrect format."
And the tasks are not properly linked to their corresponding epic.
It is also strange that the issue is inconsistent. In some cases, when I remove and re-add tasks, they link correctly, but when I repeat the same process, they are no longer linked again.
Thank you
